Many believe that healthy wearable tech is the wave of the future and LG definitely wants its piece of the pie granola bar. Today, the South Korean electronics maker announced its new Heart Rate Earphones and Lifeband Touch fitness band. While the former reminds us of a recent internet fib, we assure you that it’s the real deal. LG’s new earphones are designed to do more than crank out tunes during your spin class. These over-the-ear buds are loaded with sensors that track your heart rate by measuring blood flow signals in your ears. They can be used with a compatible smartphone via Bluetooth, however LG would prefer that you use them with its Lifeband Touch.
